脑囊虫病的CT表现

CT Manifestations of Cysticercosis of the Brain

目的 :探讨脑囊虫病患者不同时期囊尾蚴脑CT影像表现的变化及其临床意义。材料和方法 :搜集经手术和临床证实的脑囊虫病 5 2 2例 ,并对脑CT影像表现进行分型。结果 :5 5 3例脑囊虫病的CT表现如下 :Ⅰ急性脑炎型 3 5例 ;Ⅱ特征性多发小囊伴偏心头节型 13 8例 ;Ⅲ囊虫性小脓肿型 84例 ;Ⅳ单发大囊与小囊并存型 41例 ;Ⅴ多发结节状或环状增强型 13 4例 ;Ⅵ钙化型 63例 ;Ⅶ脑室囊虫型 2 7例。结论 :CT可直接显示囊尾蚴 ,反映其病理改变和演变过程 ,对脑囊虫病的定位、定性及定量判定具有重要价值。另外 ,脑CT分型可预测患者预后及指导临床用药。

Purpose: To analyse the CT features of cysticercosis of the brain at different period of the growth of the cysts and assess the clinical value of typing of brain CT image. Materials and Methods: CT appearences of 522 cases with cysticercus of the brain proved by operation and clinical data were studied and engaged in dividing types. Results: CT features included:Ⅰ type of acute cerebritis in 35 cases. Ⅱ type of multi cyst in 138 cases. Ⅲ type of single enceohalopyosis in 84 cases. Ⅳ type of big and small cyst in 41 cases. Ⅴ type of annular intensification in 134 cases. Ⅵ type of high density foci in 63 cases. Ⅶ type of brain ventricle in 27 cases. Conclusion: CT is not only the main method for showing the cyst contents but continues to provide valuable information in the treatment and prognosis of these patients.
